[2008] Access [SQL] Getting Last Row?

Hi. I'm currently stuck on a part in my application.

vb Code:

SQL = "SELECT CourseID FROM Overview"
            Adapter = New OleDbDataAdapter(SQL, Connection)
            DS = New DataSet
            Adapter.Fill(DS)
            If DS.Tables(0).Rows.Count > 0 Then
                NewTableName = DS.Tables(0).Rows().Item("CourseID").ToString()
            End If

What I'm trying to do. is when the Application Loads, I need it to get the Last INDEX in the CourseID Form and I guess add 1 to it. I forget how do it, but I believe its something to do with Reader and a Integer I guess. Like While Reader = True then Count + 1.


How would I go about doing this? Its something in here

NewTableName = DS.Tables(0).Rows(!HERE!).Item("CourseID").ToString()

That I'm going need a variable or something.

MAX?

If you're saying that you need to get the last row then, like every collection, it's at index (Count - 1).

vb.net Code:

Dim table As DataTable = DS.Tables(0)
Dim lastRow As DataRow = table.Rows(table.Rows.Count - 1)

vb Code:

Dim table As DataTable = DS.Tables(0)
            Dim TableRow As DataRow = table.Rows(table.Rows.Count - 1)
            If DS.Tables(0).Rows.Count > 0 Then
                NewTableName = DS.Tables(0).Rows(TableRow).Item("CourseID").ToString()
            End If

Can't Convert Integer into DataRow

How do I make TableRow a Integer while keeping the table.Rows(table.Rows.Count -1) ? I'm trying to get the last index then set it to add to that on a NEW TABLE

Wow I'm stupid, I just looked at my IF statment and used that

vb Code:

Dim TableRow As Integer = DS.Tables(0).Rows.Count - 1
            If DS.Tables(0).Rows.Count > 0 Then
                NewTableName = DS.Tables(0).Rows(TableRow).Item("CourseID")
            End If
